If commuting to work isn't enough to green your life, may we suggest the Cateye Hybrid Headlight? It uses a nifty, high tech, super-sustainable solar panel to recharge your light. We know, the solar powered flashlight joke is old...but this really works. Just make sure the solar panel is facing up, leave your bike in the sun and the battery will store enough juice to keep you riding all night. Click for Instruction Manual

My bike is locked up inside all the time which means that there is simply not enough light to recharge the battery so I bring the light into my office to recharge. Even two days in decent office lighting was not enough to get the battery to recharge enough to provide more than 10 minutes of light. I had high hopes but this light is not going to cut it for winter commuting.

Installed on a Catrike Trail. It took some modification of the mount and using parts from a front reflector mount to set it up on this bike. It works good. Doesn't interfere with my cup holder (for long camping trip rides) and really gets driver attention. Nice price. Nice light. I hope it lasts as well as it might.

I rode though a long dark tunnel with this light and it was very hard to see where I was going. It works well in flashing mode as a way to make your bike more visible to oncoming traffic. It would be nice if it had a couple more LED lamps (it only has one) and a USB port to recharge the battery for days when it is cloudy.

The headlight is very easy to take on or off of the bike to charge in a window if your not getting enough light in the day. I take a lot of comfort knowing that I have a solar and a backup battery for a long ride home in the dark.

I have a 15 minute commute every day and the road has street lights so I just wanted a light that would brighten the shadows. This light does just that but I would not want to use it on a dark trail as the beam is dim (runs on one AA) and narrow. For my purposes it works great and I don't need to worry about batteries. Good for what I got it for. Would like a better on-off button with a "click" feel but that's about all. Only had it for a month and don't use it in the rain (because it's dim) so I don't know how durable the solar panel will be. I hope the battery holds up because I'd like to use the flash mode on my long summer rides.

I use this light on my way home from work at 11 at night. Well made,lightweight and a great clamp that keeps the light where you want it. Solar is the way to go. Flip the switch and you still have another battery as back up if you need it. I haven't done a test to see how long the solar light will last, but for the hour long ride home. Its still as bright as when I turned it on.
